FIELD: machine building.SUBSTANCE: valve seat assembly for use in hydraulic valves is proposed. The offered valve seat includes a seal located between a valve barrel (316) and body (306), so, when the valve is in a position of closure, the outer seating surface of the gate (344), being in a sliding contact with a barrel, seats with a sliding contact on elastic gasket, closing the fluid medium flow through the valve body, and the back of the gate (344) does not contact the other seating surface. The named sealing comprises C-shape gasket and has an open part (364), faced to injected process fluid medium flowing through the valve body, and the pressure of process fluid medium forces down the seal to the seating surface (366).EFFECT: perfected design.16 cl, 8 dwg |
